How do you classify the aqueous solution acidic or basic?
By observing the [H+] ion concentration and [OH-] concentration in the aqueous solution. If the [H+] ion concentration is higher that the [OH-] ion concentration, it is acidic. Vice Versa for basic.
What is the product of H3O ion and OH- ion concentration in water?
10^-14
What solution has a grater concentration h or OH?
Depends on the pH, at low pH (below pH 7), the H+ ion concentration is greater, and high pH the OH- ion concentration is greater
How does the concentration of H plus and OH- ions determine pH?
pH = - log([H+]) , pOH = - log([OH-] , pH + pOH = 14 [X] = concentration of X
An acid increases the hydroxide ion concentration of water?
No, oppositely it DEcreases the hydroxide concentration by reaction: H+ (from acid) + OH- --> H2O

Which substances decreases the H ion concentration in a solution?
Bases, anything with the OH- ion in the formula.

How does the POH scale form PH scale?
pH + pOH = 14 pH is a measure of the hydrogen ion concentration, [H+] pOH is a measure of the hydroxide ion concentration, [OH-] pH = -log10[H+] pOH = -log10[OH-]
If the hyrdoxide ion concentartion increases what happens to the hydrogen ion concentration?
The Hydrogen ion concentration decreases. Remember that these two ion concentrations are inversely proportional, in formula: [H+].[OH-]= 1.0*10-14 or pH + pOH = 14.
How does the concentration of H plus and OH- ions determine pH?
pH = - log([H+]) , pOH = - log([OH-] , pH + pOH = 14 [X] = concentration of X

No, oppositely it DEcreases the hydroxide concentration by reaction: H+ (from acid) + OH- --> H2O
What does the hydronium ion concentration measure for a substance?
The hydronium ion concentration measures how acidic a substance is. A high hydronium ion concentration means the substance is acidic. A low hydronium ion concentration means the substance is basic. You may be more familiar thinking of it as the pH scale. At pH = 7 [H3O]+ = 10-7 and [OH]- = 10-7
What is the pH of a solution which has a hydroxide ion OH- concentration of 1.25 x 10-5?
9.097
Which ion increases in concentration when a strong base is added to water?
As a general rule of thumb, for acid solutions [H+] > [OH-], for basic solutions [H+] < [OH-], and for neutral solutions or for pure water [H+] = [OH-] This is the answer but can someone explain it to me?
Which term is applied to an aqueous solution whose hydrogen ion concentration H plus is less than its hydroxide ion concentratio OH?
basic
